Mila Kunis and Justin Timberlake are co-starring in the new film 'Friends With Benefits,' and have recently made headlines by accepting invitations to be guests at Marine Balls. As you might imagine, there was no way to avoid double entendre when both of those stories came up during their interview Monday on 'Today' (weekdays, 7AM on NBC).

'Today' anchor Lester Holt, a self-identified married and out-of-touch man, started the interview by asking the pair to explain the meaning of the phrase "friends with benefits." Timberlake joked that he thought it was about borrowing money or sugar. "I'm thinking it's about two people who want to have a regular friendship but to get together for sex," Holt said. Ding ding!

Holt also asked about the invitations extended to both Kunis and Timberlake to attend a Marine Ball. Kunis explained they'd actually be attending two separate balls. "Marines have a lot of balls," she said. Holt suggested the traditional Marine battle cry "Semper Fi" could be replaced by "Marines got balls."

Timberlake got patriotic at that point and, looking serious, said, "We want to pay honor to our country and embrace their balls."
